Li-Fi-Light fidelity is similar to the Wi-Fi technology and it is one of the future wireless communications that is emerging fastly. One of the important features of this technology is that it is fully networked, high speed, wireless and bidirectional. Today, the most trending domain is wireless communication is Wi-Fi and another notable thing is that internet users are increasing every year.

So, to obtain better speed, bandwidth, efficiency, and this Light fidelity technology has evolved. The data transmission in this Light fidelity technology can be possible just with the help of the light intensity. This is because the light intensity changes quicker when compared to the eye for capturing. The range of data transmission in Li-Fi is proved to be 100 times faster when compared to the Wi-Fi.

The working of Li-Fi technology

Li-Fi is a Visible Light Communication (VLC) system and the speed of this system is higher than any other communicative system. This Lifi uses normal LEDs and this will allow the data to get transferred and increase the speed even up to 224 Gigabits/sec. Thus, the data transmission in this technology can be carried out through the illumination. The devices used in the system are the bright light-emitting diodes. The On or Off activities of the LEDs permit some different types of data transmission in the form of binary codes however, this cannot be recognized with the human eye.

How efficient is the Li-Fi technology?

• Speed: The speed of the Li-Fi is very high and so downloading or watching the videos online will not have any issues like buffering.
• Security: The security of the data found online is one of the important concerns that have to be shown as per today. Light fidelity does not run through the partition and so, it will be more secured from the side of the hackers
• Consistent: The data transfer will be more protected when you process through the light fidelity technology
• Risk-free: Lifi technology makes use of the light waves, which is harmless. So, you can have peace of mind where you are enjoying the services without harming anyone

Applications of the LiFi Technology

The applications of lifi technology are more promising and limited to wireless communication. Some areas that this technology can be implemented are,

• Aviation
• Traffic management and road safety
• Medical applications
• Elegant lighting
• In a dangerous environment and some sensitive regions
• Interior map-reading system for helping the blind people
• Industrial areas
• Transportations
• Communication underwater

Comparison between the Wi-Fi and Li-Fi technology

• The bandwidth expansion for the Wi-fi technology is limited and in the case of Li-Fi, it is exceptional
• The data density is low in Wi-Fi technology and high in Li-Fi
• The security of the Wi-Fi is medium, but in Li-Fi is quite high
• The ecological impacts are medium in Wi-Fi and low in case of Li-Fi
• The network topologies of both the Li-Fi and Wi-Fi technologies is a point to point
• The speed of the Wi-Fi is calculated as 150 Mbps and in Li-Fi is found to be greater than 10 Gbps
• The range covered by Wi-Fi is medium and low in Li-Fi
• The power availability for Wi-Fi is low and in Li-Fi it is high
• The cost required to operate Wi-Fi is medium and it is low in case of Li-Fi

The Bottom Line

On the whole, the concept of Light fidelity technology is attracting a lot of wireless internet users because of the great features and advantages. Further, it is also beneficial for people who use laptops more for different purposes. Make use of technology and fulfill your needs appropriately.
